 91 000 74051 LATICRETE 315 PLUS is a high-performance, single-component, polymer-modified cementitious adhesive designed for bonding ceramic tiles, vitrified tiles, precast terrazzo, and natural stone on both floors and walls. It offers excellent workability and extended open time, making it ideal for professional installations where precision and flexibility are important. The adhesive can be mixed with either clean water or a latex admixture (such as LATICRETE 3701) for enhanced performance and strength.

It works well on a variety of cement-based substratessuch as concrete, concrete masonry, cement plaster, mortar beds, and even existing tile surfaces (after proper surface preparation). LATICRETE 315 PLUS supports thin-bed installation methods and can handle a maximum bed thickness of up to 12 mm. It is available in grey and white variants. 

Key Features & Benefits:

• Easy to Use: Just add water for mixing no multi-part systems or complex preparation required. 

• Extended Open Time: Provides a long pot life (up to ~3 hours) which gives installers more time to adjust tiles and ensures proper setting. 

• Non-Sag: Designed for vertical (wall) applications without sagging, ensuring tiles stay in place perfectly. 

• High Bond Strength: Exceeds the shear bond strength requirements of ANSI A118.4 and meets IS 15477:2019 Type 2 T standards. 

• Flexible & Strong: The polymer-modified formula provides good flexibility and impact resistance; can be fortified with a latex admixture (LATICRETE 3701) for even better performance, especially in exterior or demanding applications. 

• Substrate Compatibility: Bonds to a wide range of surfaces concrete, brick masonry, plaster, mortar beds, existing tiles, etc. 

• Very Economical Coverage: Around 5560 sq ft per 20 kg bag (with ~3 mm bed thickness, using a 6 6 mm notched trowel).

It is ideal for areas prone to water exposure such as bathrooms, kitchens, pools, and terraces. Its waterproof bond guards tiles against water infiltration, greatly extending the lifespan of your tile installation. With compressive strength exceeding 7 N/mm2, it guarantees lasting durability even in the most demanding environments.


Easy Mixing and Application

This adhesive, supplied in convenient 20 kg and 40 kg bags, requires a simple powder-to-water mixing ratio of 3:1 by volume. Its smooth, workable consistency enhances versatility and makes it suitable for use by both skilled professionals and DIY users. The adhesive can be applied at a 3 mm thickness for efficient coverage of 3-4 kg/m2, optimizing material consumption and minimizing waste.


Safe, Reliable, and User-Friendly

315 PLUS is non-poisonous, odorless, and safe to handle, making it user-friendly for prolonged application. It comes in both grey and white options to match diverse tile selections.
